Hi. I'm with AMP and use sierra chart with CQG data. I mainly trade tick charts with Cumulative Delta, which is big part of my strategy. I would like to find out if CQG data is good quality data for tick charts and cumulative delta.
I have read many posts about CQG data feed quality. But a lot of them are 4 to 5 years old and I don't know if the information is still relevant today, as data feeds and especially sierra chart changes all the time.
I saw a post on here where someone compared IQFeed to TT and said that you can use cum delta-up/down tick instead of cum delta-volume to compensate for poor data feed. So I have been using both at the same time, and most times they look very similar if not the same. But at times they are way different.
Can someone with experience with good quality data like IQFeed, Sierra chart data or other comment on that? Maybe CQG is good quality idk.
I included some picks from today and yesterday's close where I found most significant differences, as well as my chart and cum delta settings.
Thank you.
Can you help answer these questions from other members on NexusFi?
I've been using SC data for the past several months and have been very happy with the speed and quality. It's also relatively cheap compared to the last time I checked IQ. Full CME with market depth is roughly $40/month.
Can't speak to IQ, never used it.
I trade volume profile, so I don't know if my assessment of SC data is deep enough for what you're asking, but they do have free trials for all of their feeds. Time it right at the beginning of the month and you can get close to a month free to test it. You just pay the connection cost of $25 or so.
I think volume profile should be OK with CQG as it's pretty good data and I use it too in my trading. I use it for levels. But I'm wondering is it good enough for cum-delta because I use it to time my entries with some setups.
Anyone that compared cum-delta or other bid/ask dependent tools with CQG and other high quality data feeds.
I use SC with CQG and I must say that the data is good, from what I heard it is better on other platforms then on SC.
Since SC are pushing for their own feed now it seems almost as if(not saying they do) they are liking the problems that occur with the combo(SC+CQG).
I will give an example: A new problem occurs after an SC update using CQG, SC support will not help saying its CQG and their only solutions will be offering their own new feeds. If you need a source for this, go to their support forum and you will see this repeating itself over and over and over. Meanwhile, that same CQG feed will work like a charm on other platforms(again, the source is the SC support forum)
-After some recent SC updates the bid/offer pulling and stacking on the DOM will not work like it should. you will not be able to use it.
-on at least the CL symbol the bid and ask depth will do some weird 20 min. reset thing which will srew up your scales and automation.
-for some users, seems to be random according to SC support, there will be short disconnects, sometimes a couple a day.
- CQG API FIX will be cut off, WEB API should do.
There are, I am sure, more problems. SC will refuse support for this,which they state ahead of time, other then plugging their own feed(which is not faultless at this time also)
They also stated that they want to stop offering CQG, but they were a little fague about this.
I cannot speak for using Delta in high detail trading as I do not use it as much and I also have not compared it to much else.
So apart from comparing different feeds on their own you should know of how SC is handling those feeds which as you might agree upon could make a big difference.
